我正在处理

节点js

。我正在使用谷歌

recaptcha2

，当我看到很多示例和所有示例时，使用表单提交验证

recaptcha

。它们在操作中定义，但我的操作方法在其他导航中使用，因此我可以使用

get，post

request。我不知道如何使用

get，post

请求

recaptcha

。我想使用

get，post

请求在服务器端验证

recaptcha

我需要后端验证工作的帮助。提前谢谢

请尝试此代码

客户端代码不太安全，请同时使用客户端代码

客户端

是的，这是可行的，但如果您对recaptcha的节点模块有想法，请帮助我，因为节点模块更安全。我将尝试到现在为止，我没有在recaptcha节点模块上工作
